Stupid Healers

As a Warlock, it is my job to put a soulstone on a healer during an instance. The healer also has a job, to know how to use it. You're probably thinking "it can't be that hard to use a soulstone" but for somee, it can be a very difficult challenge. The reason a warlock does this is so if the group wipes, the healer can rez and then rez everyone else. Sometimes when the healer dies, they use the stone right away and end up dying again. Something that gets me even more upset is when they don't even use it and release their spirit to a graveyard. They usually say "oops I forgot" but how can you forget when it is right in front of you saying "Would you like to use this soulstone!!!" It is hard to be a warlock...
